Well, we didn't progress as far as we would have liked to in terms of our estimations because we thought we were dealing with a lack of clarity in terms of some of those key issues that I've outlined. But if we were to get some clarity on eligibility and transferability, the benefits refundability, if there's a policy intent to protect certain income that's provided through other sorts of plans and that was written into legislation, we could look at that as well and come back to you with a refined estimate.
But it's because what we saw, which I think reflects the wide range, we just...underneath it, we saw that there's just a lack of specificity in terms of proposed legislation. It was hard for us to do these estimates.
Jason, did you want to respond to some of the provincial variabilities in terms of offsetting costs?
